It’s been a privilege to work with [executive producer] Steven Moffat, but I think, ‘When you got to go, you go to go.’ It’s sad and I’m going to miss it.

He added, “They’ll get someone amazing [to play the Doctor]. They’ll get someone brilliant to do it. They really will. And that’s the great thing about the show is that it continues, and the strength of it survives, and it’ll get better, and it’ll get bigger, and it’ll keep up, and you’ll forget about me.”
